| Abstract: | The transmission performance of the multimode fiber frequency response in high frequency region has been analysed. A new communication system based on subcarrier multiplexing with multimode fiber has been proposed. The transmission performance of this system has been analysed and emulated. The emulation results say that the number of subcarriers used in the system gives a severity affection to the system performance; 10.2Gb/s signal can be transmitted over 1km and 2.5Gb/s signal over 4.2km in this system.The transmission distance can will be much larger by inceresing the power of the laser. |
